AUTOMATIC STOP-MOTION FOR RIBBON-LOOMS.

Application filed September 28, 1911.

To all whom t may concern Be it known that I, EMIL MILLER, a citi- Zen of the United States, residing at the borough of North Haledon, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Automat-ic Stop-Motions for Ribbon-Looms, of which the following is a specification, reference being had therein to the accompanying drawing.

The object of my invention is to provide an automatic stop mot-ion for ribbon loom that will prevent what is termed any smash up or any damage to the silk or the loom, owing to the breaking of the silk threads or any part of the operating mechanism of the loom. Therefore the objects of my invention are to provide a device that may be applied to a loom batten where banks or rows of shuttles are employed, as well as to any other hatten, and to provide a device that will combine simplicity of construct-ion, ease of operation and economy.

My invention consists of the device shown in the accompanying drawings, which form a part of this specification and represent what I consider the best means of carrying out or putting into practice the same.

In the drawings, similar letters of reference indicate like parts in the various figures.

Figure l is a plan view, enlarged, of my device, showing its application to the loom, portions being broken away; Fig. 2 is a side elevation, enlarged, of the device showing parts of the breast beam and batten; Fig. 3 is a perspective of the block and accessories which form a portion of my device; Fig. 4 is a plan view; Fig. 5 a side elevation of a loom with my device attached thereto.

In all these figures the warp, quills, harness, and reeds are omitted for the sake of clearness in the drawings.

A represents the breast beam, B the batten, S the shuttles and ithe double indicators passing through the reed, and are held stationary by compression spring -z-, which holds said indicators in their normal position. The ends of -z" of the indicators are adjusted to pass and move through openings in the adjustable blocks when a break occurs, in which event they engage and push the bent plate -ctogether with the ringed wire -doff the pin -ein the end of the block -b-. A cord "1"- passes over the guide wheel or pulleys Specification of Letters Patent.

-p-phaving one end secured to the ringed wire -dand the other end connected with the brake or pawl-lever Z- by means of the screw eye -0-. The helical spring -jis secured to the floor by means of a ring 7oby one end, and its other end is secured to the brake or pawllever -Z The drive wheel fwis provided with an adjustable ratchet-carryingsleeve -ghaving teeth -mand wf/ The block -5- through which the indicator rods --z'-z'- move is adjustable to meet different conditions by means of the slots -f-fand the screws n n-n- -n-- The double indicators pass through the reed, the double or bow portion -P-- registering with the open shed of the warp, so that the shuttle or shuttles pass to and fro through the open warp shed and through double or bow portion -P- of the indicators.

The operation of my device is as follows: as the warp-shed and the open or bow shaped portion -P- of the indicators register, the shuttles pass through the bow of the indicators and through the open warp-shed, no matter which row of shuttles are being used, and if any of the shuttles in the series should by reason of a break or other accident stop in its course, it will become fastened in the bow of the indicator, and being carried forward on the bat-ten would push or force the indicator to the position of the dotted lines shown in Figs. 1 and 2, compressing the springs -t-twhich hold said indicators ir2- in their normal position. The ends -W-zV-Fig. 3) of the indicators 7lthen in turn push the bent plate 0* together with the ring wire -doli the pin -eof the block -ZJ-. The ring wire -cZ-- when pushed off the pin -ewill release brake or pawl lever -Z-, which is normally held in passive position by the cord -rpassing over the guide wheels -pand -p-. When the said brake or pawl-lever -Z- is released as aforesaid, the helical spring fastened to the floor by the ring -ewill pull the said brake or pawl lever against the driving wheel fwwhich being supplied with the adjustable ratchet carrying sleeve -g-, said pawl lever will engage the teeth mor MX- of the said sleeve and eectively and instantaneously stop all the loom mechanism. The ends -z"z"- of the indicators --z'- are provided with a nut or head -N- to limit the rear-ward movement of the indicators. The end of the block -bis provided with recesses -r-//"- to receive the said nuts -N- and permit the bent plate -cto it snugly on the pin en and against the end of the block -b-.

Modifications may be made in the construction and arrangement of the mechanism shown in the drawings, without violating the principles or departing from the scope of my invention.

What I claim as new and desire to secure by Letters-Patent, is-

1. In an automatic stop motion for ribbon looms a device having an open, bowshaped portion which registers with the opening of the warp shed and through which the shuttle is adapted to pass while going through the warp shed, and which in case of a break is adapted to be engaged bythe shuttle and be driven by the batten, to set in operation, and in combination with, means for stopping the loom.

2. In an automatic stop motion for ribbon looms, a double indicator having an open bow-shaped portion which registers with the opening of the warp shed to permit the passage of a shuttle therethrough, the bow-shaped portion passing through the reed, the other end of the indicator passing through a block on the breast beam and means for holding the indicator in normal position'during the movement of the batten, substantially as set forth.

3. In an automatic stopping device for ribbon looms, the combination with the batten, the shuttles carried thereon, and thebreast beam of a loom, of a break indicator carried loosely by, and normally held stationary in the breast beam, having an open bow-shaped portion which registers with the warp shed and extends through the reed, in the path of the shuttle, and adapted to permit the shuttle to pass therethrough, eX- cepting in case of a break, and adapted to be operated by the batten in case of a break, to release a stopping-arm, and suchk a stopping-arm, substantially as and for the purposes set forth.

4. In an automatic stopping device for ribbon looms, the combination with the batten, and the reed and shuttles carried thereon, of a driving-wheel and an adjustable ratchet-carrying sleeve, carried by said driving-wheel, a stopping arm adapted when released to engage said ratchet and means forth.

In testimony whereof I aiiiX my signature F in presence of two witnesses.
